How many rounds? 3 yrs shooting a box a year is pretty low round count. I won't routinely shoot cheap steel ammo in any of my guns, but then I don't own a crap AK or Hipoint. The ammo works, but no one is going to convince me soft steel is good for the chamber or extractor & I have yet to see anyone torture test a pair of guns to find out. I am willing to buy the guns if someone is willing to buy the ammo??????
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
